Boot with sd_card.img and change the working directory to /run/media/mmcblk0p1.
Run applications to control the separate partitions (each exe controls one partition):
./host0.exe a.xclbin
./host1.exe a.xclbin
./host2.exe a.xclbin
Or run the application to control multiple partitions:
./host.exe a.xclbin
AI Engine graphs cannot be re-executed without rebooting on non-DFX platforms unless partition reloading is enabled in the XCLBIN. This means that, in order to rerun the application targeting either individual partitions or all three partitions, you will have to reboot the board.
For details on enabling partition reloading, please refer to Partition Reload.
